Found this on the forum when I installed my oil cooler:
Factory hard steel piping on the turbo*oil*cooler*is about 0.71" OD.
-10 AN Fittings are approx 0.62" OD. -10 Hose ID is 0.56".
-12 AN Fittings are approx 0.75" OD. -12 Hose ID is 0.69".

I should have been more specific. I need to know the ID of the stock hoses at the console so I know what size hose will fit over the factory barb fittings. I was hoping 5/8th hose will fit the barbs snuggly. 10 AN-to-5/8th hose barb adapters are easy to get for the oil cooler end, not so much for weirder sizes like 11/16th.

I cut the the hose I had (the one with the longer metal tubing end) and the Id is .625 so 5/8.

Thanks! that is exactly what I thought it was, and yes I believe the supply and return hoses are the same diameter. I'll make a new thead when I'm done, but this bit of info was the last thing I needed to put together a cheap, big aftermarket oil cooler kit.
Basically: Cut factory swagging off both stock oil lines, reuse stock 5/8th hose barb fittings on the oil cooler console. Using high pressure hydraulic crimp clamps, secure new lengths of 5/8th rubber hose to the repurposed fittings. These will attach to a pair of one piece brass male 10AN-to-5/8th hose barn fittings on the oil cooler unit its self.

The outside diameter on the metal nipples / fittings is exactly 16mm, measured at the base; the barbs are slightly larger. The inside diameter of the hoses (measured towards the middle after cutting one) is about 15.90mm so probably 16mm nominal.
